title: 1,3-Bis(2-methyl-prop-2-eno-yl)-1H-benz-imidazol-2(3H)-one.
abstract: The mol-ecules of the title compound, C15H14N2O3, possesses crystallographically imposed twofold rotational symmetry, so the asymmetric unit contains one half-mol-ecule. The fused-ring system deviates significantly from planarity; the planes of the five- and six-membered rings are twisted with respect to each other by 3.0 (1)°. In the crystal, weak C-H⋯O hydrogen bonds link mol-ecules related by translation in [010] into chains.
